Description
La présente invention a pour objet un procédé et une machine d’automatisation de fabrication d’un objet selon un procédé de fabrication additive de type solide/solide, couche par couche, tel que celui connu sous l’appellation Stratoconception®.The subject of the present invention is a process and a machine for automating the manufacture of an object according to an additive manufacturing process of the solid/solid type, layer by layer, such as that known under the name Stratoconception®.
Le procédé de fabrication additive dit de Stratoconception® élaboré par la présente Demanderesse, consiste, dans sa version la plus simple, à numériser l’objet à fabriquer, à le décomposer numériquement en différentes couches élémentaires complémentaires, à mettre en panoplies, puis à reproduire ces différentes couches par des opérations de découpes et/ou d’usinages pour obtenir des strates, enfin à, superposer et/ou juxtaposer, positionner, assembler et solidariser lesdites différentes strates pour reproduire l’objet à fabriquer.The so-called Stratoconception® additive manufacturing process developed by the present Applicant, consists, in its simplest version, of digitizing the object to be manufactured, of digitally breaking it down into different complementary elementary layers, of putting into outfits, then of reproducing these different layers by cutting and/or machining operations to obtain strata, finally to superimpose and/or juxtapose, position, assemble and join together said different strata to reproduce the object to be manufactured.
De manière accessoire, selon la complexité de la pièce à fabriquer, il peut être prévu lors de fabrication des strates, d’ajouter à la forme à réaliser, des éléments d’assemblage, tels que des extensions ou pontets, pour permettre l’indexage d’une pièce par rapport à une autre lors de l’assemblage, et destinés à être éliminés ultérieurement. On notera que dans un but également d’indexage, il peut être prévu d’utiliser des inserts, qui servent à la fois de pions de positionnement et de liens entre les strates.Incidentally, depending on the complexity of the part to be manufactured, provision may be made during the manufacture of the strata to add assembly elements, such as extensions or bridges, to the shape to be produced, to allow indexing from one part to another during assembly, and intended to be eliminated later. It should be noted that also for the purpose of indexing, it may be planned to use inserts, which serve both as positioning pins and as links between the strata.
De manière générale, les différentes strates sont de même épaisseur et découpées dans une ou plusieurs plaques d’un matériau, le positionnement et l’orientation des différentes strates sur une plaque est choisi dans un but d’optimisation, et aboutit à l’élaboration d’une panoplie de strates.In general, the different layers are of the same thickness and cut from one or more plates of a material, the positioning and orientation of the different layers on a plate is chosen for the purpose of optimization, and results in the development of a variety of strata.
On notera une difficulté supplémentaire en ce que les plaques peuvent présenter d’origine des variations d’épaisseur avec pour conséquence le non-respect des dimensions. Il est bien entendu possible d’utiliser des plaques calibrées, ou bien de recalibrer les plaques avant utilisation avec pour conséquence un accroissement des coûts.An additional difficulty will be noted in that the plates may have variations in thickness from the outset, resulting in non-compliance with the dimensions. It is of course possible to use calibrated plates, or to recalibrate the plates before use with the consequence of increasing costs.
D’autre part, il convient également de tenir compte du joint créé entre chaque strate lors de l’opération de collage, dont l’épaisseur, bien que calibrée lors du dépôt, peut aussi influer sur les dimensions finales de l’objet à reproduire.On the other hand, it is also necessary to take into account the joint created between each stratum during the bonding operation, the thickness of which, although calibrated during deposition, can also influence the final dimensions of the object to be reproduced. .
La complexité de certains objets à fabriquer, et donc des différentes strates, peut conduire à non seulement réaliser une découpe de la plaque, mais également des opérations de fraisage 3D pour créer les parties en dépouille et en contre-dépouille, en association avec le retournement de la panoplie de strates si nécessaire.The complexity of certain objects to be manufactured, and therefore of the different strata, can lead to not only performing a cutting of the plate, but also 3D milling operations to create the draft and undercut parts, in association with the reversal of the range of strata if necessary.
Un tel procédé de fabrication ne pose aucun problème de réalisation lorsqu’il est mis en œuvre de manière artisanale, il n’en est toutefois pas de même lorsqu’il s’agit de l’industrialiser et de l’automatiser.Such a manufacturing process does not pose any problem of realization when it is implemented in a traditional way, it is however not the same when it is a question of industrializing and automating it.
La présente invention a pour but de proposer un procédé permettant l’automatisation de fabrication d’un objet selon un procédé de fabrication additive de type solide/solide, couche par couche.The aim of the present invention is to propose a method allowing the automation of the manufacture of an object according to a method of additive manufacturing of the solid/solid type, layer by layer.
Le procédé d’automatisation de la fabrication d’un objet selon un procédé de fabrication additive de type solide/solide, couche par couche, se caractérise en ce qu’il comprend les étapes suivantes: décomposition numérique dudit objet selon un ou plusieurs axes, et une épaisseur, en différentes strates, par tranchage numérique,
- répartition optimisée en une panoplie desdites strates sur une plaque de matière brute,
- calcul des trajectoires du ou des outils de découpe et/ou d’usinage,
- tranchage numérique des strates, puis micro-fraisage du recto des strates de la panoplie en finition,
- retournement de la panoplie,
- micro-fraisage en panoplie du verso des strates en ébauche,
- extraction d’une première strate de la panoplie, puis déplacement dans un plan dit horizontal XY, et positionnement angulaire de ladite strate sur une zone de montage et de finition,
- dépose de colle sur ladite première strate,
- extraction d’une deuxième strate de la panoplie, puis déplacement selon ledit plan XY, et positionnement angulaire de ladite strate, et dépose et maintien sur ladite première strate, puis reproduction des étapes de collage et d’extraction pour chacune des strates restant à assembler.The process for automating the manufacture of an object according to a solid/solid type additive manufacturing process, layer by layer, is characterized in that it comprises the following steps: digital decomposition of said object along one or more axes, and a thickness, in different strata, by digital slicing,
- optimized distribution in a panoply of said strata on a plate of raw material,
- calculation of the trajectories of the cutting and/or machining tool(s),
- digital slicing of the strata, then micro-milling of the front of the strata of the panoply for finishing,
- reversal of the panoply,
- micro-milling in panoply of the back of the strata in roughing,
- extraction of a first stratum of the range, then displacement in a so-called horizontal plane XY, and angular positioning of said stratum on an assembly and finishing zone,
- depositing glue on said first stratum,
- extraction of a second stratum from the array, then movement along said XY plane, and angular positioning of said stratum, and depositing and holding on said first stratum, then reproduction of the bonding and extraction steps for each of the strata remaining at to assemble.
Selon une caractéristique additionnelle du procédé selon l’invention, une étape de détermination de la nature, de la forme et du positionnement d’éléments d’assemblage internes ou externes à l’objet est intercalée entre l’étape décomposition numérique de l’objet et celle de répartition optimisée en une panoplie.According to an additional characteristic of the method according to the invention, a step of determining the nature, the shape and the positioning of assembly elements internal or external to the object is interposed between the step of digital decomposition of the object and that of optimized distribution in a panoply.
Selon une caractéristique additionnelle du procédé selon l’invention, chacune des opérations de dépose d’une strate sur une autre après collage est suivie d’une étape de micro-fraisage en verso.According to an additional characteristic of the method according to the invention, each of the operations of depositing one layer on another after bonding is followed by a step of micro-milling on the back.
L’opération de micro-fraisage a pour but, outre la finition, de supprimer les surplus de joint issus du collage, et surtout de rectifier les défauts liés notamment à l’empilement. Cette opération est faite après empilement de chaque strate, en sorte de réajuster les paramètres dimensionnels à chaque niveau, sachant par exemple qu’un seul usinage 3D de l’objet en fin d’opération d’empilement serait probablement inopérant voire impossible à mettre œuvre.The purpose of the micro-milling operation is, in addition to the finish, to remove the surplus joints resulting from the bonding, and above all to rectify the defects linked in particular to the stacking. This operation is done after stacking each stratum, so as to readjust the dimensional parameters at each level, knowing for example that a single 3D machining of the object at the end of the stacking operation would probably be ineffective or even impossible to implement. .
Il existe déjà des automates permettant de réaliser certaines opérations de mise en œuvre d’un procédé de fabrication additive de type solide/solide, couche par couche.There are already automatons making it possible to carry out certain operations for implementing a solid/solid type additive manufacturing process, layer by layer.
Une telle machine comprend une table, de préférence de type à dépression, et des outils d’usinage montés mobiles en déplacement au-dessus de ladite table, au travers par exemple d’une traverse mobile longitudinalement au-dessus de ladite table et équipée d’outils d’usinage mobiles le long de ladite traverse, les déplacements étant gérés par une unité centrale informatique.Such a machine comprises a table, preferably of the vacuum type, and machining tools mounted to move above said table, for example through a longitudinally movable crosspiece above said table and equipped with mobile machining tools along said crosspiece, the movements being managed by a central computer unit.
Une telle machine est toutefois limitée dans son utilisation, elle ne permet pas de mettre en œuvre l’ensemble du procédé selon l’invention.Such a machine is however limited in its use, it does not allow to implement the entire process according to the invention.
La présente demande a donc également pour objet une machine permettant de pallier cette carence, et de mettre en œuvre le procédé selon l’invention.The present application therefore also relates to a machine making it possible to overcome this deficiency, and to implement the method according to the invention.
La machine permettant l’automatisation de fabrication d’un objet selon un procédé de fabrication additive de type solide/solide, couche par couche, selon l’invention, comprend une table à dépression et au moins un outil d’usinage monté mobile en déplacement au-dessus de ladite table, et elle se caractérise en ce qu’elle comporte en outre, un poste de retournement comprenant d’une part une traverse, mobile longitudinalement au-dessus de ladite table et mobile verticalement, portant un moyen préhenseur d’une plaque monté mobile en rotation selon un axe parallèle à ladite traverse, et d’autre part un moyen support d’une plaque, conçu apte à autoriser la préhension de celle-ci par l’une ou l’autre de ses deux faces, au travers dudit moyen préhenseur.The machine allowing the automation of the manufacture of an object according to a method of additive manufacturing of the solid/solid type, layer by layer, according to the invention, comprises a vacuum table and at least one machining tool mounted mobile in movement above said table, and it is characterized in that it further comprises a turning station comprising on the one hand a crosspiece, movable longitudinally above said table and movable vertically, carrying a gripping means of a plate mounted so as to be able to rotate along an axis parallel to said crosspiece, and on the other hand a support means for a plate, designed capable of allowing the latter to be gripped by one or the other of its two faces, through said gripper means.
Il est à noter que si le poste de retournement est avant tout adapté à retourner une panoplie il est parfaitement possible de le configurer pour le retournement d’une strate, selon les besoins, tout comme il permet également le retournement d’une simple plaque.It should be noted that if the turning station is above all suitable for turning an array, it is perfectly possible to configure it for the turning of a layer, according to needs, just as it also allows the turning of a simple plate.
Selon une caractéristique additionnelle de la machine selon l’invention, la traverse qui porte le moyen préhenseur du poste de retournement est montée mobile sur deux bancs, tandis qu’un porte-outil est monté mobile le long d’une traverse mobile sur les mêmes deux bancs.According to an additional characteristic of the machine according to the invention, the crosspiece which carries the gripper means of the turning station is mounted mobile on two benches, while a tool holder is mounted mobile along a mobile crosspiece on the same two benches.
Selon une autre caractéristique additionnelle de la machine selon l’invention, sur le porte-outil sont adaptables des moyens de préhension d’une pièce découpée, ainsi que des moyens d’encollage ou analogue.According to another additional characteristic of the machine according to the invention, on the tool holder are adaptable means for gripping a cut piece, as well as gluing means or the like.
Selon l’invention une variante de la machine selon l’invention, les moyens d’usinage sont également adaptables au porte-outil.According to the invention a variant of the machine according to the invention, the machining means are also adaptable to the tool holder.
En effet, les machines existantes comportent chacune, comme cela a été évoqué, une table et des outils d’usinage montés mobiles en déplacement au-dessus de ladite table. Il est possible d’adapter ces tables existantes, pour les rendre conformes à la présente invention. Ainsi, il est ajouté à ces tables existantes qui sont aptes à réaliser la découpe et l’usinage d’une plaque pour obtenir une panoplie, d’une part les moyens de retournement ainsi que le porte-outil et les outils pour la préhension et l’encollage des pièces issues de la panoplie.Indeed, the existing machines each comprise, as has been mentioned, a table and machining tools mounted to move freely above said table. It is possible to adapt these existing tables, to make them conform to the present invention. Thus, it is added to these existing tables which are suitable for carrying out the cutting and machining of a plate to obtain a range, on the one hand the turning means as well as the tool holder and the tools for gripping and the gluing of the pieces from the panoply.
Sur une machine qui ne constitue pas une adaptation à une machine existante, le porte-outil est conformé pour porter également les outils de coupe et d’usinage.On a machine that is not an adaptation to an existing machine, the tool holder is shaped to also carry the cutting and machining tools.
Selon une autre caractéristique additionnelle de la machine selon l’invention, elle comporte de plus des moyens de nettoyage de la table, associés au porte-outil.According to another additional characteristic of the machine according to the invention, it also comprises means for cleaning the table, associated with the tool holder.
Selon une autre caractéristique additionnelle de la machine selon l’invention, elle comporte des moyens de calage en X et Y aptes permettre le repérage et le positionnement d’une plaque, d’une panoplie ou d’une strate.According to another additional characteristic of the machine according to the invention, it comprises X and Y wedging means able to allow the identification and positioning of a plate, an array or a stratum.

En référence à la figure 1, on peut voir trois étapes de préparation d’une plaque de matériau M pour la fabrication d’un objet selon un procédé de fabrication additive de type solide/solide, couche par couche, tel que celui connu sous l’appellation Stratoconception®.Referring to Figure 1, one can see three stages of preparation of a plate of material M for the manufacture of an object according to a method of additive manufacturing of the solid/solid type, layer by layer, such as that known as the name Stratoconception®.
Préalablement, selon l’invention le procédé, l’objet à reproduire aura été décomposé numériquement selon un ou plusieurs axes, en l’occurrence un seul, et une épaisseur, en différentes strates, lesquelles sont agencées en une panoplie P sur la plaque M, tandis que les trajectoires du ou des outils de découpe et d’usinage ont été définies.Beforehand, according to the invention the method, the object to be reproduced will have been digitally broken down along one or more axes, in this case only one, and a thickness, into different strata, which are arranged in a panoply P on the plate M , while the trajectories of the cutting and machining tool(s) have been defined.
Sur la figure 1 l’étape A correspond au tranchage et au micro-fraisage du recto R de la plaque M en finition 3D, l’étape B correspond au retournement de la plaque M en sorte d’en exposer le verso V aux outils, et l’étape C correspond au micro-fraisage en panoplie du verso des strates en ébauche 2D, en l’occurrence cinq strates S1, S2, S3, S4 et S5.In figure 1, step A corresponds to the slicing and micro-milling of the front R of the plate M in 3D finishing, step B corresponds to the reversal of the plate M so as to expose the back V to the tools, and step C corresponds to the micro-milling in panoply of the back of the strata in 2D roughing, in this case five strata S1, S2, S3, S4 and S5.
Sur la figure 2, la strate S1 est extraite de la panoplie P, pour être positionnée, et subir d’une part un micro-fraisage de finition 3D, et un encollage de son bord supérieur.In figure 2, the stratum S1 is extracted from the panoply P, to be positioned, and undergo on the one hand a 3D finishing micro-milling, and a gluing of its upper edge.
Sur la figure 3, la strate S2 est extraite de la panoplie P, pour être déposée, positionnée et assemblée à la strate S1, l’ensemble étant ensuite exposé à un micro-fraisage de finition 3D, et à un encollage du bord supérieur de la strate S2.In Figure 3, the stratum S2 is extracted from the panoply P, to be deposited, positioned and assembled to the stratum S1, the assembly then being exposed to a 3D finishing micro-milling, and to a gluing of the upper edge of the S2 stratum.
Sur la figure 4, la strate S3 est extraite de la panoplie P, pour être déposée, positionnée et assemblée à la strate S2, l’ensemble étant ensuite exposé à un micro-fraisage de finition 3D, d’enlèvement des excès de joint, et à un encollage du bord supérieur de la strate S3.In figure 4, the stratum S3 is extracted from the panoply P, to be deposited, positioned and assembled to the stratum S2, the assembly then being exposed to a micro-milling of 3D finishing, removal of excess joints, and to a sizing of the upper edge of the stratum S3.
Sur la figure 5, la strate S4 est extraite de la panoplie P, pour être déposée, positionnée et assemblée à la strate S3, l’ensemble étant ensuite exposé à un micro-fraisage de finition 3D, d’enlèvement des excès de joint, et à un encollage du bord supérieur de la strate S4.In figure 5, the stratum S4 is extracted from the panoply P, to be deposited, positioned and assembled to the stratum S3, the assembly then being exposed to a micro-milling of 3D finishing, removal of excess joints, and to a sizing of the upper edge of the stratum S4.
Enfin, sur la figure 6, la strate S5 est extraite de la panoplie P, pour être déposée et assemblée à la strate S4, l’ensemble étant ensuite exposé à un micro-fraisage de finition 3D, afin d’obtenir l’objet 0.Finally, in figure 6, the stratum S5 is extracted from the panoply P, to be deposited and assembled with the stratum S4, the assembly then being exposed to a 3D finishing micro-milling, in order to obtain the object 0 .
On notera qu’à chaque étape, le micro-fraisage permet également de corriger les défauts selon l’axe dit vertical Z orthogonal au plan XY, liés aux potentielles variations d’épaisseurs des plaques et du joint.It should be noted that at each stage, micro-milling also makes it possible to correct defects along the so-called vertical Z axis orthogonal to the XY plane, linked to potential variations in the thickness of the plates and the seal.
En référence maintenant à la figure 7, on peut voir une machine 1 selon l’invention permettant de mettre en œuvre de manière automatique le procédé décrit ci-dessus.Referring now to Figure 7, one can see a machine 1 according to the invention for automatically implementing the method described above.
Cette machine 1 comprend une table 2, de préférence à dépression, ainsi qu’un portique cartésien 3 comprenant deux bancs 30 et 31 bordant latéralement et longitudinalement la table 2, sur laquelle peut se déplacer, dans le sens longitudinal, une traverse mobile sur laquelle est monté mobile le long de celle-ci un porte outil 33, tandis qu’à une extrémité de la table 2 sont entreposés des outils 34 destinés à être adaptés au porte-outil 33.This machine 1 comprises a table 2, preferably with depression, as well as a Cartesian gantry 3 comprising two benches 30 and 31 bordering laterally and longitudinally the table 2, on which can move, in the longitudinal direction, a movable crosspiece on which is movably mounted along it a tool holder 33, while at one end of the table 2 are stored tools 34 intended to be adapted to the tool holder 33.
On notera que la représentation de la machine n’est pas limitative, elle peut par exemple être conçue pour que les déplacements longitudinaux soient réalisés au niveau de la base.It should be noted that the representation of the machine is not limiting, it can for example be designed so that the longitudinal movements are carried out at the level of the base.
La machine 1 comporte également un poste de chargement/retournement 4 coopérant avec les deux bancs 30 et 31, et qui comprend deux chariots 40 et 41, mobiles en déplacement sur les bancs, respectivement 30 et 31, une traverse 42, mobile verticalement sur les chariots 40 et 41, ainsi qu’en rotation axiale, et portant des moyens préhenseurs 43. Le poste de retournement 4 comprend également une console 44, disposée à l’extrémité de la table 2 opposée à celle où sont entreposés des outils 34, et qui comprend essentiellement deux équerres 45 écartées l’une de l’autre pour libérer un espace central, permettant le passage des moyens préhenseurs 43.The machine 1 also comprises a loading/turning station 4 cooperating with the two benches 30 and 31, and which comprises two carriages 40 and 41, movable in displacement on the benches, respectively 30 and 31, a crosspiece 42, movable vertically on the carriages 40 and 41, as well as in axial rotation, and carrying gripper means 43. The turning station 4 also comprises a bracket 44, arranged at the end of the table 2 opposite that where the tools 34 are stored, and which essentially comprises two brackets 45 spaced apart from each other to free up a central space, allowing the passage of the gripping means 43.
Dans une variante de construction, les deux équerres 45 peuvent être remplacées par les dents 46 d’une fourche rétractable dans la table 2, telle que cela est représenté sur la figure 22.In a construction variant, the two brackets 45 can be replaced by the teeth 46 of a retractable fork in the table 2, as shown in Figure 22.
En référence maintenant aux figures 8 à 19 on va décrire des étapes du procédé de fabrication, mis en œuvre avec la machine 1.Referring now to Figures 8 to 19 we will describe the steps of the manufacturing process, implemented with the machine 1.
Sur la figure 8, les moyens préhenseurs 43 ont prélevé une plaque de matériau M sur un emplacement stockage pour la déposer sur la table 2, le positionnement dans un plan dit horizontal XY étant réalisé par calage en butée.In FIG. 8, the gripper means 43 have taken a plate of material M from a storage location in order to deposit it on the table 2, the positioning in a so-called horizontal plane XY being achieved by wedging in abutment.
Sur la figure 9, le recto R de la plaque M est tranché et usiné en finition 3D au moyen des outils 34, pour créer la panoplie P.In Figure 9, the front R of the plate M is sliced and machined in 3D finish using tools 34, to create the range P.
Les figures 10 à 14 concernent le retournement de la panoplie P. Sur la figure 10, la plaque M est saisie par les moyens préhenseurs 43 puis, figure 11, déposée sur la console 44 en appui par son verso V puis, figure 12, les moyens préhenseurs 43 sont positionnés sous la plaque M, entre les équerres 45, pour la saisir par son verso V, enfin figure 13, la plaque M est retournée pour aller être déposée sur la table 2 sur son recto R, figure 14.Figures 10 to 14 relate to the reversal of the panoply P. In Figure 10, the plate M is gripped by the gripper means 43 then, Figure 11, placed on the bracket 44 supported by its reverse side V then, Figure 12, the gripper means 43 are positioned under the plate M, between the brackets 45, to grasp it by its reverse side V, finally figure 13, the plate M is turned over to be placed on the table 2 on its front side R, figure 14.
Il est à noter que sur la figure 13 on peut voir que pendant la phase de retournement de la plaque M, un nettoyage de la table 2 est réalisé en temps masqué, le porte-outil 33 ayant saisi un moyen de nettoyage 35 de type racloir et aspirateur, qui est déplacé en surface, pour repousser et aspirer les résidus d’usinage hors de la table 2, en l’occurrence pour les faire tomber dans un réceptacle 20.It should be noted that in Figure 13 it can be seen that during the phase of turning over of the plate M, a cleaning of the table 2 is carried out in masked time, the tool holder 33 having entered a cleaning means 35 of the scraper type. and vacuum cleaner, which is moved on the surface, to push back and suck up the machining residues from the table 2, in this case to make them fall into a receptacle 20.
Sur la figure 15, le verso V de plaque M est usiné en ébauche 2D, tandis que sur la figure 16 une strate S1 est prélevée dans la panoplie P et, figure 17, est déposée sur la table 2 à côté de la plaque M dans une zone de montage/empilement.In figure 15, the reverse side V of plate M is machined in 2D roughing, while in figure 16 a stratum S1 is taken from the panoply P and, figure 17, is placed on table 2 next to plate M in an assembly/stacking area.
On notera que la zone de montage/empilement et celle d’usinage représentées sur les figures peuvent être interchangeables, comme cela est par exemple représenté sur la figure 22. Sur la figure 18 une strate S2 est prélevée dans la panoplie et déposée à côté de la strate S1, tandis que sur la figure 19, une strate S3 est prélevée dans la panoplie et déposée sur les strates S1 et S2 après usinage puis encollage de celles-ci.It will be noted that the assembly/stacking zone and the machining zone represented in the figures can be interchangeable, as is for example represented in FIG. 22. In FIG. the stratum S1, while in FIG. 19, a stratum S3 is taken from the array and deposited on the strata S1 and S2 after machining and then gluing them.
Sur la figure 20, on peut voir l’objet O terminé tandis que le porte-outil 33 et le moyen de nettoyage 35 évacuent les résidus.In Figure 20, the finished object O can be seen while the tool holder 33 and the cleaning means 35 evacuate the residues.
En référence maintenant à la figure 21, on peut voir une variante de la machine selon l’invention, et plus particulièrement une adaptation à une machine existante.Referring now to Figure 21, one can see a variant of the machine according to the invention, and more particularly an adaptation to an existing machine.
Cette machine existante comporte une table 5 à laquelle est associé un portique mobile 6, comprenant deux montants latéraux 60 et 61, mobile le long de la table 5, et une traverse 62 qui les relie, qui est donc mobile au-dessus de la table 5 et le long de laquelle peut se déplacer un porte-outil 63 apte à saisir des outils 64 d’usinage stockés en extrémité de la table 5.This existing machine comprises a table 5 with which is associated a movable gantry 6, comprising two side uprights 60 and 61, movable along the table 5, and a crosspiece 62 which connects them, which is therefore movable above the table. 5 and along which can move a tool holder 63 capable of gripping machining tools 64 stored at the end of the table 5.
Selon l’invention, la table 5 existante est complétée, pour lui permettre de reproduire le procédé selon l’invention, par l’adjonction d’une part d’un portique 3 comprenant deux bancs 30 et 31 une traverse mobile 32, pour déplacer un porte-outil 33, qui est toutefois réservé aux opérations de préhension, d’encollage et de pressage des strates, ainsi qu’au nettoyage de la table 5; et d’autre part d’un poste de retournement 4 comprenant deux chariots 40 et 41, une traverse 42, des moyens préhenseurs 43, et une console 44.According to the invention, the existing table 5 is supplemented, to enable it to reproduce the method according to the invention, by the addition on the one hand of a gantry 3 comprising two benches 30 and 31 a movable crosspiece 32, to move a tool holder 33, which is however reserved for the operations of gripping, gluing and pressing of the strata, as well as for cleaning the table 5; and on the other hand a turning station 4 comprising two carriages 40 and 41, a crosspiece 42, gripper means 43, and a console 44.
Dans le mode de réalisation représenté, la machine est associée extérieurement à un poste d’usinage 7 permettant de réaliser les finitions, et notamment, mais non exclusivement, l’enlèvement des extensions ou pontets qui ont servi à l’indexage.In the embodiment represented, the machine is externally associated with a machining station 7 making it possible to carry out the finishes, and in particular, but not exclusively, the removal of the extensions or bridges which were used for the indexing.
Il est à noter que le poste 7 peut être avantageusement remplacé par l’association d’un outil d’usinage au porte-outil 33 par l’intermédiaire d’un porte-outil à deux axes de rotation, ou bien d’une tête birotative, pour un usinage sur cinq axes. Cette configuration permet notamment d’intégrer toutes les fonctions dans une même machine.It should be noted that the station 7 can be advantageously replaced by the association of a machining tool with the tool holder 33 by means of a tool holder with two axes of rotation, or else of a head bi-rotary, for five-axis machining. This configuration makes it possible in particular to integrate all the functions in the same machine.
En référence maintenant à la figure 22, on peut voir selon une autre variante, notamment de la machine représentée sur la figure 7.Referring now to Figure 22, one can see according to another variant, in particular of the machine shown in Figure 7.
Sur cette machine est ajoutée une traverse mobile supplémentaire 8, à laquelle est associée un porte-outil 80 dédié à l’encollage et à la manipulation des strates en vue d’assemblage, en sorte de pouvoir dissocier les fonctions usinage/nettoyage et encollage/empilement. Cette dissociation autorise un traitement en temps masqué plus efficient.On this machine is added an additional movable crosspiece 8, to which is associated a tool holder 80 dedicated to the gluing and manipulation of the strata for assembly, so as to be able to separate the machining/cleaning and gluing/ stacking. This dissociation allows more efficient masked-time processing.
